I am having difficulty booting Windows 8 on my HP Envy 4 Ultrabook. Firstly when I try to login to Windows using my Windows 8 password it says "The User Profile Service service failed the sign-in. User profile cannot be loaded".

Then following advice from other online support forums including this one, on restarting the computer then pressing F8 repeatedly I get the following message: "Boot device not found. Please install an OS on your hard disk. Hard disk (3F0).

I have tried to get into my laptop model:dv6-1310ei Prod no:vs080ea#acq,serial no:cn94769wf,pavilion dv6,,after typing my password,the result I get is "user profile service failed to login,user profile cannot be loaded....

My laptop logged me off while using it and I tried log back on but I keep getting this message "user profile service failed the log on , user profile cannot be loaded." But it lets me in as a guest but cannnot let me in as an administrator. I'm 100% certain my password is correct.

I returned from a 2 week holiday to find that I could not logon to my laptop. During the time I was away the laptop was powered down. When I enter the correct password to logon I get: "The User Profile Service service failed the logon. User profile cannot be loaded." message. I tried powering the laptop for 3 hours then tried to logon again but without success. How do I get around this?

I have a Compag Presario CQ57 with windows7, "it said that the profile couldn't be loaded," so the question is how do I get in my computer to open it up to work on this problem or resolve it or how do I over ride the guest side so that I can get in on that side I forgot the password I set up on that side. how to get into the other user side I forgot the login password for this guest side I set up.

I am still not able to use my laptop as the thing won't or can't load user profile, all I get is the message user profile service failed the logon. I ran the F12 at start up and performed the extended diagnostic test which tells me everything is just peachy.

I have an acre aspire 5535. I cannot login and keep going round in circles with the message which says "the user profile service failed to login. User profile cannot be loaded". I have switched off and opened again but no change.

I bought a used HP envy x from amazon, windows 8. When it's delivered I tried to open it, there's only one user account, and it has a password... What should I do? I tried the password reset thing, but it didn't work?

I have a HP Envy 4 - 1046tx Ultrabook and the operating system is Windows 8.1 64-bit. While downgrading to Windows 7 64 bit I was unable to find the hard drives. In the installation screen it showed me "No drives were found. Click Load Driver to provide a mass storage driver for installation.".

I downloaded all the versions (from latest to the oldest) of Intel Rapid Storage Technology drivers and tried installing them one by one but they didn't work and still the hard drives aren't visible. But if I use a Windows 8 installation disc and install the driver the hard drives are visible.

I need my computer to display the hard drives by default without requiring a SATA driver. How do I do that? My chipset manufacturer is Intel and the model is Ivy Bridge HM77.

I have an envy m6 touchscreen that is giving me problems that i can't solve. It has been great up until recently. i was using my laptop last nite when suddenly it turned off but i didn't think that the battery shoukd have been dead yet. its acting as if the bat is empty and plugging it in just turn on the orange led by the power plug. when i press the power button it flashes for a second but the screen does nothing and it doesn't actually turn on.I'm using my phone to attempt to find a solution atm which is very frustrating. adding to the stress is the fact that i have school work projects and a midterm project on it that I need to finish.Almost forgot to mention it started doing a few other odd things over the last week such as the touchscreen going nuts registering phantom touches endlessly until i close/hibernate/shutdown it.

I recently received my new XPS 14 (L421x) ultrabook. Out of the box, this machine has a 500Gb C: drive labeled "OS" and a second 110Gb SSD D: drive labeled "Data". Windows 8 is installed on the C: drive. There is absolutely nothing on the D: drive.

Does this sound right? I would have thought that you would want to have the OS on the SSD and boot from that (much faster?) drive.

I received my new Inspiron Utrabook today . Everything was fine for the first time that I booted. When I tried booting the second time, it's stuck on the Dell screen. Tried hitting F2 as per the suggested posts but to no avail. And how do you remove the battery ?

i got a hp dv2000 and sometimes when i start it up and it gets to the user selection screen i cant find my cursor to select my user account. I keep moving my finger on the touch pad but cant find it. I have to hold the power button down it will shut off then i have to pull out the battery start it up and the cursor is now there this has happened like 5 times already what would cause this?

I have Thinkpad W500, Windows 7 Professional, 64bit. When I turn on laptop, i forget when (before or after Windows loading) it brings me to the FingerPrint icon. This part is ok because the laptop seems to continue booting without my clicking it which I prefer. (I don't even have my own FingerPrint saved in laptop and I find that strange. I bought this W500 used). After FingerPrint icon disappears, the User or Admin Icon is shown on screen. That picture needs to be clicked for laptop to continue booting up or loading up. No password required, just click the icon. I'd like for laptop to just bootup without doing anything, and go to the desktop page automatically (like all my other thinkpads).

How can I turn off that second Icon or feature? Is it a User or Admin icon? I'm only user of laptop so I don't need feature to use a password or to click the Icon.

I have an ENVY 17 (3277nr) with windows 8.1 in it but I'm unable to update it since several months ago so I decided to reinstall the OS so I went to the windows site that lets you download an ISO image of windows 8.1 to burn it into a disc (right now I dont have a 4gb usb at hand but is also possible).

I already burned the disc by right clicking the ISO and selecting 'burn disc image' and changed the boot options but every time I turn on my computer all I see is a single underscore and then the regular windows 8 boot screen.

I already visited wbesites in this regard and I've read things like the windows 8 UEFI thing (not on my laptop since I've upgraded from w7) and the security settings on the BIOS but none of them seem to fix the problem.

Additional details:

Oddly, when trying to open the burned dvd it only says 4.37gb out of 4.37gb, do you think my dvd drive might be damaged?

I have an Aspire 5742 factory loaded with Windows 7 and it worked for 3 years. Now, Microsoft is sending me 'Unauthorized Windows' messages. The hardware has not changed. Microsoft checked and said my OEM product key is fine. Restoring to a previous point failed to fix problem. I just ordered the eRecovery DVD. Is there a way to fix this without wiping the system and starting over? I have a LOT of software installed that I will hate to lose. BTW - my best guess is that malware caused this

My computer won't play sounds at all (videos online, downloaded music, games on my computer, everything).

This doesn't happen all the time. I'm not sure but I think it usually happens when I use my computer for a long time (1-2 hours). It starts working again when I restart my computer but it stops working later and I have to restart my computer again.

I have a "HP Pavilion TouchSmart 14-n005eo Ultrabook" running windows 8.1. This last Friday my computer got stuck and when I tried to reboot it said that something was wrong with windows and gave me the alternatives to fix it. I first tried to backup trough the program but got a Bluescreen (System thread exception not handled (iaStorA.sys). I then tried to just restore the Windows part (not effecting my files) but I got Blue screen. I then moved on to a full system reset (with my recover DVD that I fortunately had made just a couple of days before the crash) but after completed all 5 discs the computer rebooted and told that the system restore wasn't completed so I tried again, but I got the same problem.

The last thing I have tried is to make a factory reset and now (after the 5 disc) it started to reboot and a information that told that HP software were about to get installed came up. I left the computer to finish the install and when I checked later on it was turned of so i turned on the PC and after the message "Wait" I got Blue screen again (System thread exception not handled (iaStorA.sys)) and the same happens when I restart the computer.

I have a HP 6t-1200 CTO Ultrabook with the Radeon HD 8750M and Intel 4000 switchable graphics.

Problem: When I am operating with Windows 8 they function normally, but upon updating to Windows 8.1 the AMD drivers fail to be able to initiate and D3D.

1. Most current driver is dated 2013-01-142. Generic drivers do not recognize the hardware3. Drivers for other HD 8xxx series based HP laptops do not resolve the problem

Current workaround: Open the Catalyst Control Center and go to switchable graphics application settings under the power tab. Switch anything that uses DirectX to run in power saving mode, this will run those applications using the intel 4000 graphics which has a more current driver that works with Windows 8.1.

Solution: For now I believe that the only solution is to wait for HP and Microsoft to work together on creating a newer driver. Once that newer driver is released it should resolve the problem. The other solution is to permanently stick to Windows 8 and not update to Windows 8.1. This is a bit more difficult though since Microsoft pushes 8.1 very aggressively. There might be a way to make the notifications and automatic attempts to update stop, but I have not looked into that solution.

I am hoping to buy an HP Envy 15 j102saI want to fit an mSATA SSD as well as the hard drive1. Does this model have a free mSATA bay?2. Is it possible to boot off the SSD and will it require a boot loader from the HDD?
